Cleaning “cocktails” creating risk says fire brigade

Mixing household cleaners to make “cleaning cocktails” is putting people at a risk, the London Fire Brigade (LFB) has warned. Accidentally combining common household cleaners can cause a dangerous chemical reaction and “unleash” dangerous fumes.

The LFB says that since 2023, it has responded to over 150 incidents involving cleaning chemicals that  triggered a dangerous reaction. Chemical incidents call on the brigade to deploy specially trained and equipped officers to identify and deal with the dangerous cleaning cocktails.

The LFB’s lead officer for dealing with hazardous materials, Group Commander Matt Hayward, has warned Londoners to read the labels and instructions of any cleaning product.

“The label will always tell you how to safely use the product, and the risks of mixing it with other things,” he said. “Always follow the instructions on the container to ensure you are using your cleaning products safely. People often think that cleaning products will be twice as effective when mixed, but it can be a recipe for disaster. If you do accidentally mix chemicals and start to feel unwell, make sure you leave your property immediately and stay out whilst you call 999 for assistance. We have crews that are trained and equipped to deal with these incidents, so we are ready to help if required.”

The LFB has the following safety tips for cleaning products: 

• Read the instructions and beware of any warning labels. 
• Keep chemicals in their original containers with all original labels. 
• Do not pour chemicals into the same container or use one cleaner right after another, as it may create dangerous gases. 
• Always store harmful chemicals away and out of reach of children. 
• Read and follow the instructions on products and always use them as they are intended to be used. 
• Always open windows in the rooms in which you are using any chemicals to allow for natural ventilation. 
• Be sure to completely wash off one cleaning product before applying a second cleaning product, so that there is no mixing of chemicals. 
• Consider professional tradespeople if over-the-counter cleaners or drain unblockers are unsuccessful. 
• Contact your council about how to safely dispose of unused chemicals.
